Will you ever be cruising on the racetrack or just to it or is it a trailer car? If you're driving the car there and then you do a tune-up before you race then you might want the E curve for gas mileage and turn off vac for race...lmao... i
Trailer car and the pro billet is what I plan on running but recently acquired an e-curve and was thinking about playing around with it. Curious to see everyone’s opinion.
